PVA Bags

These are tapered bags made from Polyvinyl-Alcohol, which are used to isolate a cast or an object before laminating a socket over them. They first appear thick and no-elastic, but after they have been wrapped in a damp towel for 20 minutes they become very stretch and elastic allowing them to be pulled over an object, taking it's shape exactly when the air is vacuumed out. We also provide PVA film for anyone who might want to make custom sizes
